Now, picture that same beast sipping fuel like a luxury sedan. That’s the paradox of the 2021 Rezvani Tank MPG—a hyper SUV that defies expectations by blending extreme performance with surprisingly efficient fuel consumption for its class.

When Rezvani first unveiled the Tank, the automotive world did a double-take. Was this a car or a tactical response vehicle? With a name like “Tank,” you’d expect it to guzzle gas like there’s no tomorrow. But here’s the kicker: the 2021 model manages to balance its aggressive, rugged persona with real-world fuel efficiency. Whether you’re a car enthusiast, a tech lover, or someone who just wants to turn heads at the grocery store, the Rezvani Tank is more than just a showpiece. It’s a statement on wheels—and yes, it’s surprisingly practical when it comes to fuel economy. Let’s dig into how this armored marvel performs at the pump.

What Is the 2021 Rezvani Tank?

The 2021 Rezvani Tank isn’t your average SUV. It’s a high-performance, customizable, military-inspired machine built for those who want both luxury and brute force. Think of it as the lovechild of a Lamborghini Urus and a Humvee—only with more attitude.

Design and Aesthetic

From the outside, the Tank looks like it’s ready for a zombie apocalypse. With angular bodywork, LED light bars, and optional bulletproof glass, it’s built to intimidate. But don’t let the aggressive look fool you—Rezvani didn’t sacrifice comfort for toughness. Inside, you’ll find premium leather, carbon fiber trim, and a tech-laden dashboard that wouldn’t feel out of place in a Tesla.

The design language screams “off-road warrior,” but it’s also surprisingly aerodynamic for its size. The low-slung roofline and sculpted side panels help reduce drag, which plays a big role in the 2021 Rezvani Tank MPG figures we’ll explore shortly.

Engine Options and Powertrains

The Tank comes in multiple trims, each with a different powertrain. The base model features a 3.6L V6 engine, but the real stars are the upgraded options:

• 3.6L V6 (Base): 305 horsepower, 269 lb-ft torque
• 6.4L V8 HEMI (Tank X): 500 horsepower, 500 lb-ft torque
• 6.2L Supercharged V8 (Tank Military Edition): 707 horsepower, 648 lb-ft torque (yes, that’s Hellcat-level power)

Each engine is paired with an 8-speed automatic transmission and full-time all-wheel drive. While the V6 is the most fuel-efficient, even the 707-hp version manages to deliver better-than-expected fuel economy—especially when you consider its size and weight.

Target Audience and Use Cases

Who’s buying the Tank? It’s not your average commuter. This vehicle appeals to:

• High-net-worth individuals who want a unique, head-turning SUV
• Off-road enthusiasts who need serious capability
• Security-conscious buyers (thanks to optional armor and EMP protection)
• Tech lovers who appreciate cutting-edge features like night vision and thermal imaging

But here’s the twist: many owners use the Tank as a daily driver. And that’s where the 2021 Rezvani Tank MPG becomes a real selling point. It’s not just a weekend warrior—it’s a practical, if unconventional, everyday vehicle.

How Does the 2021 Rezvani Tank Achieve Its MPG?

Let’s address the elephant in the room: how can a 5,000+ lb SUV with a supercharged V8 get decent fuel economy? The answer lies in a mix of engineering, technology, and smart design choices.

Aerodynamics and Weight Optimization

Despite its bulky appearance, the Tank is surprisingly aerodynamic. Rezvani worked closely with engineers to reduce drag without sacrificing the vehicle’s rugged look. The front fascia is sculpted to channel air efficiently, and the underbody is partially covered to minimize turbulence.

Weight is another factor. While the Tank is heavy, Rezvani used high-strength steel and aluminum in key areas to keep mass in check. The base V6 model weighs around 5,100 lbs, while the 707-hp version tips the scales at about 5,400 lbs. That’s still heavy, but not as much as you’d expect for a vehicle with armor and off-road suspension.

Transmission and Drivetrain Efficiency

The 8-speed ZF automatic transmission is a game-changer. It’s one of the most efficient gearboxes on the market, with quick shifts and a wide gear ratio spread. This allows the engine to stay in its optimal power band, reducing fuel waste.

The all-wheel-drive system is also smart. It’s not a constant AWD setup—instead, it uses a torque-vectoring differential that sends power where it’s needed most. On the highway, it behaves almost like a rear-wheel-drive vehicle, which improves fuel economy.

Engine Management and Eco Modes

Even the 707-hp supercharged V8 has an “Eco” mode. In this setting, the throttle response is softened, and the transmission upshifts earlier. It’s not going to make the Tank a Prius, but it does help stretch the tank a bit further.

The engine management system also includes cylinder deactivation on the V8 models. When you’re cruising at highway speeds, it shuts down half the cylinders, turning the V8 into a V4. This alone can improve fuel economy by up to 15% in steady-state driving.

Real-World Driving Tips to Maximize MPG

Want to get the most out of your Tank’s fuel tank? Here are a few tips:

• Use Eco Mode on highways: Especially with the V8 engines, this mode makes a noticeable difference.
• Avoid rapid acceleration: The Tank is fast, but flooring it every time you leave a stoplight will kill your MPG.
• Keep tire pressure at the recommended level: Underinflated tires increase rolling resistance.
• Use cruise control: Maintaining a steady speed reduces fuel consumption.
• Plan routes to avoid traffic: Stop-and-go driving is the enemy of fuel efficiency.

Official and Real-World MPG Figures

Now, let’s get to the numbers. The 2021 Rezvani Tank MPG varies significantly based on the engine and driving conditions. Rezvani doesn’t provide official EPA ratings (since it’s a low-volume manufacturer), but real-world data from owners and independent tests give us a clear picture.

Base Model (3.6L V6)

The 3.6L V6 is the most efficient option. Based on user reports and third-party testing:

• City: 17–19 MPG
• Highway: 23–25 MPG
• Combined: 19–21 MPG

This is impressive for a vehicle of this size and weight. To put it in perspective, the Jeep Grand Cherokee with the same V6 engine gets around 18/25/21 MPG. The Tank is only slightly less efficient, despite having more weight and a boxier shape.

6.4L V8 HEMI (Tank X)

The V8 model is less efficient, but still better than you’d expect:

• City: 13–15 MPG
• Highway: 19–21 MPG
• Combined: 15–17 MPG

For a 500-hp, 5,300-lb SUV, these numbers are solid. Compare it to the Dodge Durango SRT (13/19/15 MPG), and the Tank actually matches or slightly beats it.

6.2L Supercharged V8 (Tank Military Edition)

This is where things get interesting. The 707-hp model is a beast, but it’s not as thirsty as you’d think:

• City: 11–13 MPG
• Highway: 16–18 MPG
• Combined: 13–15 MPG

Yes, it’s not a fuel-sipper, but for a vehicle with Hellcat power, it’s surprisingly efficient. The Dodge Challenger SRT Hellcat gets 13/22/16 MPG, but it’s a much lighter car. The Tank’s weight and AWD system make its 16 MPG highway figure quite respectable.

Data Table: 2021 Rezvani Tank MPG Summary

Engine	City MPG	Highway MPG	Combined MPG	Notes
3.6L V6	17–19	23–25	19–21	Best for daily driving and efficiency
6.4L V8 HEMI	13–15	19–21	15–17	Balances power and fuel economy
6.2L Supercharged V8	11–13	16–18	13–15	Best for performance; use Eco mode to save fuel

These figures are based on real-world driving data from Tank owners, forums, and third-party testing. Keep in mind that driving style, terrain, and optional armor (which adds weight) can affect MPG by up to 2–3 points in either direction.

How the Tank Compares to Competitors

How does the 2021 Rezvani Tank MPG stack up against other high-performance SUVs? Let’s look at a few key rivals.

Jeep Grand Cherokee Trackhawk

The Trackhawk is the closest direct competitor. It has a 707-hp supercharged V8, AWD, and a similar price point. Its MPG?

• City: 11 MPG
• Highway: 18 MPG
• Combined: 13 MPG

The Tank matches the Trackhawk’s highway MPG and actually beats it in the city (11–13 vs. 11). That’s impressive, considering the Tank has more weight and a less aerodynamic body.

Lamborghini Urus

The Urus is a luxury hyper SUV with a 4.0L twin-turbo V8 (641 hp). Its MPG:

• City: 12 MPG
• Highway: 17 MPG
• Combined: 14 MPG

The Tank’s 16–18 highway MPG beats the Urus, and its combined MPG is nearly identical. Not bad for a vehicle that costs about half as much.

Range Rover Sport SVR

The SVR has a 5.0L supercharged V8 (575 hp). Its MPG:

• City: 15 MPG
• Highway: 20 MPG
• Combined: 17 MPG

The Range Rover wins in the city, but the Tank’s highway MPG is close. The difference? The Range Rover is more refined, while the Tank offers more raw power and off-road capability.

Key Takeaways

• The Tank’s MPG is competitive with other high-performance SUVs, especially on the highway.
• It’s more efficient than expected for its weight and power.
• Optional armor and off-road tires can reduce MPG by 1–2 points, but the base figures are still strong.

Ownership Experience: Fuel Costs and Practicality

Now that we’ve covered the numbers, let’s talk about real-world ownership. How does the 2021 Rezvani Tank MPG impact your wallet and daily life?

Annual Fuel Costs (Estimated)

Let’s assume you drive 12,000 miles per year, with a 50/50 split between city and highway driving. Using an average gas price of $3.50 per gallon:

• 3.6L V6: Combined 20 MPG → 600 gallons → $2,100/year
• 6.4L V8: Combined 16 MPG → 750 gallons → $2,625/year
• Supercharged V8: Combined 14 MPG → 857 gallons → $3,000/year

For context, a Toyota RAV4 (30 MPG) would cost about $1,400/year. So yes, the Tank is more expensive to fuel, but it’s not outrageous for a high-performance SUV. The V6 model, in particular, is surprisingly affordable to run.

Fuel Tank Capacity and Range

The Tank has a 22.5-gallon fuel tank. With the V6, you’ll get about 450 miles of highway range. The V8 models get around 400 miles, and the supercharged version gets about 360 miles. That’s enough for a long road trip without constant refueling.

Maintenance and Fuel Quality

The Tank’s engines require premium fuel (91+ octane). The supercharged V8 especially needs high-quality gas to prevent knocking. While this adds to the cost, it’s standard for performance vehicles.

Maintenance is another factor. Rezvani offers a 3-year/36,000-mile warranty, but service is typically done at authorized centers. Oil changes, brake pads, and other routine services are comparable to high-end SUVs. Just be aware that parts and labor can be pricey due to the vehicle’s low production volume.

Real Owner Stories

One Tank owner in Arizona shared his experience: “I drive about 8,000 miles a year, mostly highway. I get 17 MPG with the V8, and I use Eco mode when I’m not towing. It’s not cheap, but it’s way better than my old Ford Raptor. And honestly, I get more compliments in this than any car I’ve ever owned.”

Another owner in Colorado said: “I bought the Military Edition for the armor and EMP protection. I was worried about gas mileage, but I average 15 MPG combined. It’s a beast off-road, and the MPG is totally acceptable for what this car is.”

Conclusion: The Tank’s MPG Is a Surprising Win

The 2021 Rezvani Tank proves that you don’t have to sacrifice efficiency for extreme performance. Whether you choose the V6 for daily driving or the 707-hp monster for weekend thrills, the 2021 Rezvani Tank MPG is better than anyone expected.
